I guess the answer is a qualified yes. Wratten & Wainright was an English company that made dry platess in the last quarter of the 19th first qtr of the 20th century. Kenneth Mees joined the firm and developed dyed gelatin filters. In 1912 Geo. Eastman bought them up moving Mees to start Kodak research in Rochester.

I have two sets of 4 inch W&W filters and they are made much like Kodak Series filters are: two pieces of glass with a gelatin film in between. W&W made several grades of large filters from Grade A through C or D and from 2x2" up to 5x5" Grade A was double the cost of Grade B I have grade B and they are find 70+ years later.

I think Kodak Series filters would probably compete favorably when put up head to head with Grade B W&W filters. I think they are cheaper because they don't need to be optically perfect over a larger surface area and economy of scale.

Not sure I was clear.

Series IV to IX Kodak Wratten filters in 'B' glass with metal rim, lots of colors.

vs

Series V to VII Kodak Pictorial filters in the same mount, red, yellow or green.

Question : are/were Pictorials low-cost or low-quality Wrattens ?

Charlie Kammerman is more knowledgeable about Kodak than even George Eastman.

Of the top of his head, he had never heard of Kodak Pictorial filters, but he has several displays and catalogs and is looking into the subject.
